Title: Innovations of Yasushi Fukutomi
Introduction
Yasushi Fukutomi is a notable inventor based in Sagamihara, Japan. He has made significant contributions to the field of optical measurement and microscopy. With a total of 2 patents, his work has advanced the understanding and application of precision measurement techniques.
Latest Patents
Fukutomi's latest patents include a "Method and apparatus for point diffraction interferometry." This innovative method involves forming a substantially ideal spherical wave using a point light source-generating unit. The light flux, composed of this spherical wave, passes through a test sample and is divided into two light fluxes using an optical path-dividing element. One of these light fluxes is converted into a reference light beam, allowing for the detection of interference fringes. This technique enables the measurement of wavefront aberration without being affected by disturbances such as system vibrations.
Another significant invention is the "Scanning probe microscope." This device achieves atomic-level resolving power and includes a probe microscope unit for measuring the fine constitution of a sample surface. The optical microscope unit allows for the observation of optical images of the sample. The probe microscope unit is encased in a noise and electromagnetic wave-shielded box, designed in the shape of a triangular cone, which enhances its measurement capabilities.
